Just finished cam install on my 2500hd 6.0 had an efi tune put in pcm. My main problem is the truck will idle fine and run 210 degrees. Can idle around in the pasture just fine. Once I accelerate truck temp jumps straight to 260 and truck shuts down never to restart again. OBD loggs the same codes and I am on my 3rd pcm. Engine will not even crank. Codes logged p0606, uo107 and p1258.. My selector light for trans stays on park and will not move. Do I have a ground wire problem? I'm just about to have it towed to the dealership.
